Sort of. Wind is very good at stirring things up, but you can still see differences in places where there are a lot of plants (1-2%). This things needs CO2 to function and that means it needs concentration so the more CO2 to start with the better.
Fortunately this is small and electric is something we already move to cities in large quantities. Putting it in a city makes sense - assuming it works and is safe of course.



Nice thought experiment, but the physics of how batteries work mean we can’t. The theory behind batteries only allow for so much improvement, and will never get close to gasoline/diesel. For most driving batteries are good enough, but they will never be as good as gasoline despite how inefficient ICEs are.
